Installation
The following parameter assumptions are made:
GPIB secondary addressing is not supported.
The default GPIB primary address is 1. The GPIB primary
address can only be changed from a connected Tektronix
USBTMC-USB488 compliant instrument designed to support the
TEK-USB-488 GPIB to USB Adapter, such as a DPO4000 Series
oscilloscope.
The GPIB Program Message Terminator (PMT) is the GPIB end of
input (EOI) line and is not con
fi gurable. Messages that assert EOI
concurrent with a new line (hexadecimal 0a) character as the last
data byte are supported. This means that both EOI and EOI NL
program message terminations are supported and that the NL-only
termination is not supported.
USB hubs are not supported. You can connect only one
USBTMC-USB488 compliant instrument to the USB Host port of
the adapter at any time.
The GPIB on/off state is online when there is an active
USBTMC-USB488 connection. You cannot change the GPIB
on/off state after the connection is established.
